(CNN) - Rush Limbaugh responded to Roberta McCain's criticism of his tough radio persona Thursday, joking over the fact "McCain's mother is dumping on me."

"She is absolutely right" in her assessment that that she belongs to a different Republican Party than he does, Limbaugh said during his radio show: "The Republican Party she belongs to gets shellacked election after election after election."

In an appearance on The Tonight Show With Jay Leno Wednesday, the outspoken 97-year-old mother of Sen. John McCain said, to cheers from the audience, that Limbaugh "does not represent the Republican Party that I belong to."
"I belong to the Republican Party," she said. "What he represents of the Republican Party has nothing to do with my side of it. I don't know what the man means, I don't know what he's talking about."

On his show Thursday, Limbaugh made clear he found the criticism quite amusing.
